In an ideal inductor that has no resistance or capacitance, as the current increases energy flows into the inductor and is stored there within its magnetic field without loss, it is not released until the current decreases and the magnetic field collapses.
On the short scale, there are 12 zeros in a trillion (1012). It is 1,000,000,000,000. The traditional long scale, still used in many areas of the world, advances number names by millions, with intermediate names for the thousands (milliard, billiard, trilliard).
The system used in the U.S. is not as logical as that used in other countries (like Great Britain, France, and Germany). In these other countries, a billion (bi meaning two) has twice as many zeros as a million, and a trillion (tri meaning three) has three times as many zeros as a million, etc. But the scientific community seems to use the American system.. So, it depends on where you're coming from, so to speak.
